Description
Calculate a supplied correct-word fraction and percentage.
Hearing records depend on frequency, laterality, masking status, calibration and level reference. A no-response label differs from a measured threshold, while an air-minus-bone gap requires comparable test conditions. Device charge arithmetic and scalar signal offsets do not establish hearing status or suitable care.
Calculate a supplied correct-word fraction and percentage.
When to use this tool
Use Speech Test Correct Word Fraction when you already have correctWords, presentedWords and need to calculate a supplied correct-word fraction and percentage.
How to use the tool and how it works
- Enter correctWords, presentedWords. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read correctFraction, correctPercent. Use the output convention below.
Require positive safe presentedWords and safe correctWords in [0,presented]; return correct/presented and 100*correct/presented.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| correctWords | Correct Words | Required. Safe integer; minimum 0. |
| presentedWords | Presented Words | Required. Safe integer; minimum 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| correctFraction | correctWords/presentedWords. | Required. Finite number. |
| correctPercent | 100*correctWords/presentedWords, on a 0..100 rather than 0..1 scale. | Required. Finite number. |

}Limitations and assumptions
- The denominator is supplied presented words. The tool does not validate a speech test, account for list difficulty, assess hearing or prescribe intervention.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review original audiograms, instrument settings, test records and the complete clinical context. Use an appropriate professional assessment for interpretation; local unit conversions and supplied labels do not choose tests, presentation levels or intervention.
